How can I change the icon of my app after it’s installed?
In previous versions, I remember I could “reinstall” the app and also change its icon during that process.
In the latest version, however, reinstalling the app simply reinstalls it—without giving me the option to change the app icon.

Thanks for asking! To customize app icon, you need to create a custom app.
